No fluff—here’s what matters.
👉 Your machine either matches the cutter… or it doesn’t.
Must be standard skid steer mount (SSL).
👉 Use 50% of tipping load
Not brochure numbers.
👉 Must be within range — NEVER over
Over =
❌ motor failure
❌ heat
❌ no warranty
👉 Must be at or below rating
Too much =
❌ blown seals
❌ shorter life
👉 Wider than your tracks
BUT:
👉 Borderline machine? Size down.
👉 Flow = speed
👉 Pressure = torque
Every machine is different.
👉 Virnig gives motor options so you:
Higher speed = cleaner cuts
BUT…
👉 Mass keeps cutting
👉 You need speed + torque + flywheel weight
Most problems come from:
👉 Bad match
👉 Poor design
Get it right:
✔ Smooth
✔ Fast
✔ Long-lasting
Get it wrong:
❌ Expensive
👉 Match it. Size it right. Run it right.
